ABSTRACT:
A projectile controlled by way of an optical fiber includes a body having an airframe; an outlet in the projectile body adapted for allowing the optical fiber to be pulled out of the body; a bobbin for holding the optical fiber, the bobbin being tapered so that a helix formed by the optical fiber will not scrape over the bobbin; and a tapered chamber within the projectile body, the chamber having a first end connected to the outlet and a second end having the bobbin located therein. The diameter of the chamber is smaller than the diameter of the helix formed by the optical fiber at the exit plane of the bobbin measured without the constraining chamber, and the tapered chamber has a polished and lubricated inner surface. Additionally, the chamber may have a tube extension joined by springs for extending the chamber past the outlet.
